Lime is a citrus fruit with a green skin and sour, aromatic flesh that originates from Southeast Asia and is now cultivated in the tropics, Africa, and Central America. Lime trees can grow up to 5 meters tall, and the fruits are juicier than lemons and highly valued for their intense aroma. They are also referred to as the "lemons of the tropics" and are an ingredient in many famous cocktails as well as in Mexican and Southeast Asian cuisine.
